4x+2y=2
3x+y=4
you need to eliminate either the x or the y
leave the first equation alone
multiply the second equation by 2 to get the coefficient of y the same so it can
be eliminated
4x+2y=2
6x+2y=8
to eliminate the y's you need to change the signs of the second equation and add
-2x= -6
x=3
go to either equation and substitute 3 for x to solve for y
y=-5
